Plenty of people — strangers, fans, critics — have reacted to Tuesday's news that Michigan State football coach Mark Dantonio was retiring.
No doubt one in particular resonated.
Spartans basketball coach Tom Izzo, a longtime friend and colleague, made his almost-sorrowful feelings known on social media.
"It's a sad day for me, if you want the truth," he said in a tweet posted on @MichiganStOnBTN.
When Dantonio became the program's all-time career winning coach in September, a video tribute was played on the Spartan Stadium scoreboard.
